2000 Ford F150 Fuse Blowing Out

If it pops that quick, there has to be a dead short. Can you hear any snaping when the key is first turned on?

Thanks for the quick response! I don't recall hearing any clicking when the key is turned forward. However, the digital odometer has been working intermittently over the past three years. It will be off when the truck is started, and sometimes come on later.

Hi:
As far as the odometer, that is a common problem. The short, on the other hand, isn't. Have someone listen under the hood when you do it to see if they he can hear a noise when you turn the key. It may be helpful to do it in the dark. That way, if there is a spark, you will see it.

thanks for the help! i checked all of the relays and everything else in the fuse box under the hood... i even looked at the wires running under the truck... i looked at all the wires under the dash and the hood... i found a braided ground wire running from a cluster of wires behind the battery to the firewall on the passenger side of the engine compartment... stupid thing was barely screwed in... now i'm back up and running!

That will do it. I'm glad you found it. They're not that easy to find, so I know you had a headach on your hands.

Let us know if you have questions in the future. One more thing, did the ground take care of the odometer?

Sorry for the delay in answering... When I first started the truck - after the repair - the odometer worked fine. Since then, it has been on and off again... More off than on.

I have been having the same problem. The first time it happened, I took it in for diagnosis, but they could not find what blew the fuse. It has happened about three times since then. I have to turn everything off, replace the fuse and then start it. It happened again this past Tuesday in traffic. I managed to get off to the side of the road. I turned everything off, like I normally do but the fuse kept blowing. I was down to my last fuse when I realized I still had power coming in because I had not opened up any doors to release the initial power that lingers until you open the door. Traffic was heavy so I got down in the floor and was changing it with out getting out of the truck. When I opened the door and then changed the fuse, I was back on the road again. So far my thoughts are a $.99 fuse is a lot cheaper than a diagonistic bill each time it happens.
